反应限制集群集群聚合使用三种不同的模型。这些模型的模拟表明：（i）迁移率依赖过程的分形维数对模型的细节敏感，（ii）反应核K（ii）≥ i 1.1，除非存在缓慢的交叉到i 1.0，（iii）有效团簇尺寸分布指数τ的值更接近2.0而不是1.5，以及（iv）如果两个集群将加入的概率取决于它们的移动性，则可以预期τ的值小于1.5。
Reaction-limited cluster-cluster aggregation is investigated using three different models. Simulations of these models suggest that (i) the fractal dimension for mobility-dependent processes is sensitive to the details of the model,(ii) the reaction kernel K (ii)∼ i 1.1, unless there exists a slow crossover to i 1.0,(iii) the effective cluster-size-distribution exponent τ has a value closer to 2.0 than 1.5, and (iv) if the probability that two clusters will join depends on their mobility, then a value of τ less than 1.5 might be expected.
